The blind auditions are over, and tonight on The Voice, it is time for the battle rounds to begin!

"The battle rounds are great. That's where the blind auditions have been put to bed as far as getting people's attention purely on your voice, and then it's a matter of bringing a little bit of stage presence," coach Christina Aguilera says. "You see their competitive spirit come to bat."

In addition to the coaches, The Voice has quite the lineup of guest mentors this season to help out the different members of Team Christina, Team Blake Shelton, Team Cee Lo Green and Team Adam Levine!

Jewel is so excited to be a part of the new season as she and husband Ty Murray watched it last year and loved it.

"I think what makes the show stand apart is these are really judges who know what they're talking about," Jewel says. "They've been through it. It's fun to see them coach and cultivate and really mentor the talent, and not just critique them and tear them down." A little dig at a certain British reality show judge, perhaps?

Check out the video below for more of Jewel's interview. And don't miss the battle rounds tonight at 8 p.m. ET on NBC!
